To all whom it may concern:

Be it known that I, WILLIAM H. BREW, a citizen of the United States,residing at \Vashington, in the District of Columbia, have inventedcertain new and useful lm provements in Soap-Dispensing Devlces; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates particularly to a semi-fluid or pasty soapdispensing device, but as will appear from the following specificationtaken in connection with the accompanying drawings the device isapplicable to be used as a container and dispensing means for othersemi-fiuid or pasty compositions.

It is generally conceded that the use of soap in cake form in publiclavatories is unsanitary and a prevalent source of infection, while theuse of soap in liquid form has not been found altogether satisfactory,owing to the ingredients required for the manufacture of the liquid soapand further owing to the necessary waste of the liquid when beingdispensed from the container.

In order that the use of a semi-fluid or pasty soap may be entirelysatisfactory, it is essential that an etficient container be employedwhich can be easily and, quickly operated by the user in such mannerthat none of the soap contents of the container are wasted.

This invention, therefore, has for its object to provide a container anddispensing device for semi-fluid or pasty soap and the like, soconstructed and arranged that the soap contents can be quickly andeasily dispensed and in such manner that the flow of the contents fromthe container will automatically cut off so as to prevent waste of thesoap.

With this object in view the invention consists in the novelconstruction and arrangements of the container and particularly in thenovel construction and arrangement of the dispensing tube closure andsoap cutting off means.

The invention further consists in the novel construction of the pistonor follower, and the invention further consists in certain novel detailsof construction and in combination of parts, all of which will be firstfully described and afterward specifically pointed out in the appendedclaims.

Referring to the accompanying draw- 1ngsz- Figure l is an elevation of asoap Container and dispensing device constructed in accordance with thisinvention.

Fig. 11 is a longitudinal sectional view ta ken through Fig. 7, and

F g. 12 is a top plan View of the device.

Like numerals of reference indicate the same parts throughout theseveral figures, in which 1 indicates the device, which includes acylindrical container 2 having a bottom 3 w th an opening 4 thereincommunicating path the dispensing tube 5, which as shown in the drawingsis square in cross-section.

6 indicates the container cap threaded at 7 for connection with thecontainer 2, said cap being centrally threaded at 8to receive thethreaded stem 9, which stem 9 is preferably secured to a flange or plate10 having perforations 11 for the reception of suitable screws orfastenings.

12 indicates the piston or follower which of the underface being fiat asshown in the drawings. A disk 17 of pliable material,

such as felt, leather or the ike, is arranged and fastened in theconcaved portion 14 0f the plate 13, while the convexed plate or disk 18is applied under thepliabledisk17,

the whole being fastened together by fasten-f ings 19 as shown',inthedrawings.

Referring again to the dispensingtube which as. before stated is squarein cross-section, it will be seen that the same has a closed bottom 20and preferably an elongated dis 'pensing aperture 21 in one side of thetube 5 and near the closed bottom 20, while opposite sides of the tube20 have at their bottom edges a small lateral extension 22 to act as astop to limit the downward movement of the dispensing tube closure andcut off 23.

Referring particularly to this dispensing tube closure and cut off 23,it will be seen that the same is square in cross-section, closelyconforming to the shape and sides of the square dispensing tube 5 andarranged for free vertical sliding movement on the square dispensingtube 5. One side of the closure and cut off 23 is extended below the endof the dispensing tube 5, which extension is indicated by thenumeral 24,the bottom edge 25 thereof being beveled as shown, the beveled edgebeing itself beveled to provide a knife or cutting edge to facilitatethecutting off of the soap and provide for an easy passage of theextension through the soap passing or protruding from the dispensingaperture 21.

In order to further provide for the close conformation of the knifeedged extension 24 of the closure or cut off 23, I provide in the sideof the said closure or cut off 23 opposite to the knife edged extension24, two small vertical cuts 26, which forms in effect a resilient tongue26 and this tongue is slightly bent inwardly against the adjacent sideof the dispensing tube 5, sufficiently to cause the knife edgedextension 24 to closely hug the side of the square dispensing tube 5provided with the soap dispensing aperture 21. Sufiicient tension isgiven the closure or cut off 23 to hold the knife edged extension ineffective position and at the same time to allow for a free slidingmovement of the closure and cut off 23 on the square dispensing tube 5.

Having thus fully described the several parts of this invention, itsoperation is as follows:

The container 2 is filled with a suitable semi-fluid or pasty soap uponremoval of thethreaded cap '6 and the piston. or fol lower 12. As amatter of fact the container .lS disassembled by unscrewing thecylindricalcontainer 2 from the threaded cap 6 and the threaded cap 6 isthreaded down on the stem 9 to the piston 12. The piston and cap: areagain applied to the container and upon rotation of the cylinder 2, saidcylinder and cap arethreaded up on the stem 9,

causing the bottom 3 of the cylinder to approach the piston or follower12. This action, of course, places the contents of the container undercompression. This rotating 7 action is' effected by grasping the hand"wheel-28, which is secured to and movable with the closureand cut-off23 and as the "said closure and cut-off is freely slidable on thedispensing tube 5, the dispensing aperture 21 in said tube 5 isuncovered by the closure 25, which allows the soap contents of thecontainer to be forced through the dispensing aperture 21 preferably inthe form of ribbon.

Instantly that the hand wheel 28 is released the closure and cut-off 23drops into a normally lowered position, the knife edged extension 25cutting through the ribbon of soap and dropping in its normally loweredposition at the same time effectually closin the dispensing aperture 21and cutting 0 further supply from the container.

By means of this construction the dispensing of a semi-fluid or pastysoap or like contents is eifected in a simple and efficient manner andwith no waste whatever, as the hand of the user is' directly under thewheel 28 when rotating the same and thus in perfect position to receivethe dispensed contents from the device, while the supply isautomatically cut off as soon as the hand of the user is removed fromthe hand wheel 28.

Referring to the modification illustrated in Figs. 7 to 12 inclusive, itmust be stated that where it is desired to place or attach the device onthe table portion of a lavatory or wash-basin, it is quite essentialthat the dispensing tube be positioned at the top of the receptacle,which positioning of the dispensing tube and operatin wheel requires aslight rearrangement of tie parts as heretofore described; In theconstruction referred to it is preferable to have the container 2removable from the top 6 and bottom 3 of the device. The parts beingsecured together in any simple manner, such as for instance, by bayonetjoints 6', as shown in Fig. 7. It is also preferable to provide a gib 2'vertically of the inner surface of the container 2 and to provide thepiston or follower 12 with a slot 12, so as to hold said piston 12against rotation. In

this instance, the threaded stem 9 threads eeann:

9 is provided with a reduced upper-portion 9, which passes through aperforation 10 in the top 6, the hand wheel 28 being arranged on theupper-end of the stem 9. B means of this construction the piston or 0lower 12 is operated within the container to compress the contentsthereof by manipulation of the hand wheel 28.

In this construction, I prefer to either cast or otherwise formintegrally with the top 6 the dispensing tube 5, which as shown in Fig.10 is of goose neck formation having" a straight depending portion 5',which is preferably square in cross-section, as shown in Fig. l1,sa1dstraight portion 5' being provided with the dispensing aperture 21 andarranged on the cut-0E and closure 23 and depending therefrom by a stem23 is a weighted-ball or other element 24', the same havin suflicientweight to cause the cut-off and c osure 23 to operate eficientlyautomatically under the influence of gravit in the same manner asheretofore describe Having thus fully described the invention, it isapparent that a semi-fluid or pasty soap or like contents and dispensingmeans can be constructed in accordance with this invention at slightexpense.

It is also apparent that the construction of the follower or pistoninsures a strong compression and a consequent positive dispensing of thecontents of the receptacle, as by my arrangement the pliable disk 17under influence of compression is distorted out of its trueconcavoconvexed form and lies against the annular flat face portion ofthe disk 13, which causes a slight increase in the diameter andcircumference of the pliable disk 17 sufiicient to insure a perfectlytight engagement of the disk 17 with the walls of the container 2.

It is further apparent that the construction is of a particularly simplenature and that there are no weak or delicate parts, such as springs andthe like to become deranged and thereby render the device inoperative.

It is further apparent that the container as shown and described issusceptible to certain changes in construction and arrangement of theparts and I consider myself clearly entitled to any and all such changesand modifications as fall within the limit and scope of the appendedclaims.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is-
